在已有 app_options 的基础上提供根据当前浏览器页面进行条件判断的功能

已经验证了通过类似 AppleScript 的进程间通信来实现的思路，不需要安装附加插件（除了 Firefox，后面会说明原因）

最简单的方法当然是直接调用 AppleScript 解释器：

(* 理论上适用于任何 Chromium-Based *)
tell application "Arc" to return URL of active tab of front window

(* Safari *)
tell application "Safari" to return URL of current tab of front window

Foundation 中已有 NSAppleScript，调用即可（但我没有找到“在切换 tab 时触发”等事件监听，所以可能需要轮询

也可以通过 ScriptingBridge 直接用 Objective-C 写逻辑：

#import <Foundation/Foundation.h>
#import "browser.h"

int main(int argc, const char * argv[]) {
    @autoreleasepool {
        BrowserApplication *browser = [SBApplication applicationWithBundleIdentifier:@"company.thebrowser.Browser"];
//        BrowserApplication *browser = [SBApplication applicationWithBundleIdentifier:@"com.apple.safari"];
//        for (BrowserWindow *window in [browser windows]) {
//            NSLog(@"window %ld: name is %@", [window index], [window name]);
//        }
        BrowserWindow *window = browser.windows.firstObject;
        // Chromium-Based 只有 activeTab，Safari 只有 currentTab，以此简单区分
        BrowserTab *tab = [window respondsToSelector:@selector(activeTab)] ? window.activeTab : window.currentTab;
        NSLog(@"active tab is %@ %@", tab.name, tab.URL);
    }
    return 0;
}

这个 browser.h 是我根据 Arc 和 Safari 原始导出的 protocol 修改合并而来的，导出 protocol 的命令是：

# 两个 CLI 都随 Xcode 安装
sdef /Applications/Arc.app/ > Firefox.sdef
sdp -fh -o Arc.h --basename 'Browser' Arc.sdef

如果有能避免维护一个 protocol 头文件的方法是否会更好？我没写过 Objective-C，网上搜索到的 id 类型似乎仍然需要“某处”有该方法约定存在，而不能完全省略 protocol 声明

Firefox 的问题是它的文档表明它需要从 document 属性获取 path 信息，但是从下面这张截图可以看到这个功能并没有做出来：

从 bugzilla 页面 来看这个问题貌似从 Firefox 3 开始有人注意到现在都没人真正弄出来……这个页面靠后的帖子提到一个 workaround 是用 插件 将 URL（默认是只有域名部分，不过对匹配网站来讲应该完全足够）放到窗口标题。AppleScript 是能正常获取到窗口标题的，因此最后就能获得当前网站。

輸入法進程接收到的客戶端是系統的輸入法服務生成的proxy，所以能有特別的輸入優先級，也因此無法使用其他API（相信蘋果有保護隱私的考慮在）。所以你說的從根本上就無法實現

我尝试手动赋予输入法进程「控制其他 app 权限」确实无法生效，如果真要实现可能需要一个 helper daemon 然后与其进行 ipc

另外如果都要单独的 helper daemon 了，那可能不如直接做个浏览器插件
